   电子灭蚊灯的工作原理是利用蚊子的趋光性,将蚊子吸引过来,使其触电身亡,采用高效诱蚊灯管,对蚊虫等有害飞虫都有高效引诱作用,通过静电电击能够瞬间杀灭飞虫;电子灭蚊灯电路设计限流,低耗电,高效能,只要接通电源即可使用,无任何化学物质挥发。气流吸蚊灯带风扇,是通过气流将蚊子吸附,从而致其死亡。气流吸蚊灯体积较小,可以随身携带,一般用于家庭。

  那么灭蚊灯是用什么供电的呢,灭蚊灯里面通常是一个12V或者5v工作的风扇,和一个蓝色的LED灯,通过把交流的220v转变成直流的12v或者5v,常见的办法是用阻容降压电路,缺点是发热大过不容易过EMC优点是便宜;另外就是用非隔离芯片,直接交流220v整流后能过芯片电路转变成12v或者5v的直流电压,驱动一个140MA左右的风扇和一个90MA的LED灯。

Mosquito lamp power supply scheme, 220v to 12v chip, AC drive a 140MA fan and a 90MA LED lamp
 
   The working principle of the electronic mosquito killer lamp is to use the phototaxis of the mosquitoes to attract the mosquitoes to make them electrocuted. The high-efficiency mosquito lamp is used to attract mosquitoes and other harmful flying insects. It can kill the fly instantly by electrostatic shock Insect; electronic mosquito killer lamp circuit design current limit, low power consumption, high efficiency, as long as it is connected to the power supply can be used without any chemical substances volatilization. The airflow suction mosquito lamp is equipped with a fan, which absorbs the mosquitoes through the airflow, causing death. The airflow mosquito-absorbing lamp is small in size and can be carried around, and is generally used in homes.
 
  So what is the power supply for the mosquito killer lamp? The mosquito killer lamp is usually a 12V or 5v working fan, and a blue LED lamp. By changing the 220V AC to 12V or 5V DC, the common way is The disadvantage of using a resistance-capacitance buck circuit is that the heat generation is greater than the EMC. The advantage is cheap; in addition, it uses a non-isolated chip, which can be converted into a 12V or 5V DC voltage through the chip circuit after direct AC 220V rectification, driving a 140MA or so Fan and a 90MA LED light.
 
  Mosquito lamp power supply scheme, 220v conversion 12v chip, wide voltage input 45v-265v, with over temperature protection, over current protection, short circuit protection, the maximum current output can reach 1A, can adjust the current through cs current limiting resistor, ripple small work Low energy consumption has passed European regulations and American regulations.
